Specification of Letters Patent. Application filed September 22, 1905.Serial No. 279,644

Patented. Jan. '8, I907.

To a, whom Lt may concern: 3

I Be it known that I, J ULIUsR. WIIMLINGER;

a'citiz'e'n of the United States, residingat Brooklyn, in the county ofKings and State of New York, have inventedcertain new and usefulImprovements in Metal Filing, :of which the following is aspecification.

My invention relates to metal pilings and the object of my presentinvention isto provide a piling construction which may be used fordriving concrete or other piles or for any purpose to which sheet-pilingis adapted.

My improved piling construction comprises a structure formed of metalsheets,

preferably corrugated and secured together in pairs in such a mannerthat they may be driven bodily. The sections thus formed are provided ator near their ends with means for locking the adjoining sections. Forthe sake of clearness I will hereinafter refer to these sections aspiles.

Referring to the drawings attached hereto, Figure 1 is a transversesectional plan of a single pile formed of two corrugated plates securedtogether. Fig. 2 is a transverse sectional plan of a portion of twopiles locked together. Fig. 3 is a transverse sectional plan of aportion of two piles driven at an angle to each other and locked attheir intersection.

In my improved metal-piling construction each unit or pile is formed oftwo corrugated plates or sheets each having semicircular bends orcorrugations 1 and flat portions or webs 2 between the saidcorrugations. The sheets are so fastened together that the corrugationswill face each other and form cells 10 10, having substantially circularcrosssection; but they may have any other suitable cross-section. Theyare secured together by means of rivets 12 12, which pass through thewebs 2, the two sheets being thus brought into contact with each other.Two sheets thus form a unit or pile. These piles are locked to theadjoining piles when in position of use. The corrugations 3 at one endof each unit are of a smaller radius than that of the corrugations 1 atthe other end by the thickness of the material used in order that whenthe piles are driven in locked position the eell formed by thecorrugations 3 will readily fit and slide within the cell formed by themarginal corrugations 1, as

' shown in Fig. 2. If, however, the material of which these piles aremanufactured is sufficiently thin, the bends or corrugations mayadjoiningunits maybe done either by eX' panding thecorrugations 1 orflbycompressing the corrugations o'fthe iadjoining unit enough to allow theend of the unit to bein-' serted, as will be readily understood.

The web 2 adjacentto theco'rrugation 3 at the end of each unitis.provided with ,a look.-

ing member composed of a fiat portion, {1 and "a curved portion 5 at anangle thereto; Thev locking members are secured to the body-of the pileby means of rivets 12 12, which pass through the flat portions 4 and thewebs 2 of the plates. The curved portions 5 overlap and lock the edgesof the corrugations 1 of the adjoining pile, as shown in Fig. 2.

In order to form corners or angles, a portion of the marginalcorrugation 1 of one pile is removed or omitted, as shown at 6 in Fig.3, and projects between the adjacent locking member 5 and thecorrugation 3 of the intersecting pile, while the other locking memberis arranged with an extension 8, which extends over and locks thecorrugations 1, as at 9.

The piling may be driven in sections, such as shown in Fig. 1, and afterthey are in the required position the cells 10 may be em tied of thematerial therein by means of t e sand-pump, hydraulic jet, or otherdevice employed for this purpose, and, if necessary, the cells may befilled with concrete or other material. If, however, the mass to bepenetrated is easily compressible, the corrugations 1 1 and 3 3 may beprovided with shoes or jaws attached thereto and the cavity filledbefore or after driving, according to the requirements of the case. Whenit is desired to adapt this improved piling construction to the purposesof sheet-piling, the corrugations 1 1 and 3 3 may be made much smalleror more numerous for the same width of pile, or the configuration of thecorrugations may be modified. For instance, the corrugations may beflattened, and the webs 2 may be bent into a curve reversed to that ofthe corrugations 1 1 and 3 3 after the well-known form of corrugatedsheets used for roofing.

What I claim as new, and desire to secure by Letters Patent, is

1. A metal-piling construction comprising corrugated plates securedtogether in pairs and provided with looking members attached to the saidplates.

2. A metal-piling construction comprising all have the same radius, andthejlo clri'ng of i IOC corrugated plates secured together in pairs atthe meeting edges of the corrugations and provided with looking membersattached to the said plates.

3. A metal-piling construction comprising piles having cells, and meanssecured to said piles for locking them together.

4. A metal-piling construction com rising piles having cells and websbetween t e said cells, means secured to said webs forlocking the pilestogether.

-'5. A metal-piling construction comprising piles having open spaceswebs between the said open spaces and splices for securing the saidpiles together.

6. A metal-piling construction comprising piles having cells, the wallof one of the said cells adapted tofitinto one of the cells oftheadjoining pile, and means for locking the 20 said pilesto ether.

7. A meta piling construction comprising piles having cells and websbetween the said cells,-the walls of one of the said cells adapted tofit into one of the cells of the adj oining pile, splices fastened tothewebs of the said pile, for locking the piles together, the saidsplices being each composed of a fiat portion secured to the web and acurved locking member.

in testimony whereof I aflix my signature 1n presence of two witnesses.
